The geometries of nonmarine-sandstone reservoirs of the subsurface Mesaverde Group in northwestern Colorado were estimated on the basis of sedimentologic studies. The accuracy of the estimates was subsequently assessed by geophysical tests and reservoir-engineering studies, such as vertical seismic profiles, hydraulic-fracture diagnostics, pressure tests (drawdown/buildup, production, and interference tests), and tracer tests. After the effects of natural fractures on these subsurface tests are accounted for, the tests provide indications of reservoir boundaries, internal heterogeneity, and continuity that are compatible with sedimentologic predictions.

The Three-Dimensional Facies Architecture of Terrigenous Clastic Sediments and its Implications for Hydrocarbon Discovery and Recovery
While there has been much interest in recent years in concepts of sequence stratigraphy, this book focuses on stratigraphic units that are, in general, an order of magnitude smaller than sequences. A knowledge of such architectural detail is of considerable significance in the development of detailed, scaled facies models for depositional environments, and is of paramount importance in the efficient design of advanced petroleum recovery projects. This book is the outcome of a SEPM Research Symposium held at the annual meeting of the Society in San Antonio, Texas, April 1989. The intent of the meeting was to bring together modern research on facies architecture, and to apply this research to the investigation of reservoir heterogeneities and production problems.
